New pistils?!

Got a dinafem blue cheese that is 70 days flower exactly tomorrow. I thought she was ready to harvest but she has just threw up new white pistils! I have only gave plain water this week, no nutes. Should I harvest anyway or give it another week? If so do I feed once then plain water, or just give plain water for another week? Sorry for the crap pic!

Seems long for an indica dom, dinafem claim 50 days! Also I don't see many Amber trichs yet!

FoxTails,,,,totally normal

I thought it was foxtails! It's just the fresh white pistols hav threw me abit coz I thot it was ready to harvest! I know breeders say quicker finishing times than it is, but I'm already 20 days past the 50 day stated time. Should I just cut soon as she ambers up abit and not judge by the pistils?
